Problema Solution
Quik call charges $0.18 per minute for long-distance calls. Econo phone totals your phone usage each month and rounds the number of minutes up to the nearest 15 minutes. It then charges $7.90 per hour of the phone usage, dividing this charge into 15-minute segments if you used less than a full hour. If your office makes 5 hours 3 minutes worth of calls this month using the company with the lower price, how much will these calls cost?
Answer provided by our tutors
5 hours 3 minutes = 5*60 + 3 = 303 min
Quik call charges $0.18 per minute thus for 303 min it will charge 303*0.18 = $59.4
Econo phone charges $7.90 per hour of the phone usage, dividing this charge into 15-minute segments
5 hours 3 min rounded to the nearest 15 min is 5 hours
the charge for 5 hours is 5*7.90 = $39.5
since 39.5 < 59.4 follows Econo phone is the company with the lowest price and the cost of the calls is $39.5.
